let the center of circle be h,k
then dist between h,k and 1,2 = radius of small circle + radius of variable circle

also dist between 1,4 and h,k < r+radius of big circle

CorrodedCoffinOP•12/3/24, 11:34 AM

radius of small circle =1 , big = 10

i did the same things as shown in M-2 , but i am getting b=11/2 not a=11/2
just a diff of notations ig

CorrodedCoffinOP•12/3/24, 11:54 AM

SirLancelotDuLac•12/3/24, 12:09 PM

SSirLancelotDuLac And yeah it will be b and not a=11/2

CorrodedCoffinOP•12/3/24, 12:11 PM

b being semi major axis right?

CCorrodedCoffin b being semi major axis right?

SirLancelotDuLac•12/3/24, 12:11 PM
